Potent peptides inhibit HIV entry into cells
Date:10/10/2007

this technique, researchers analyze how an extremely bright beam of x-rays, available only at synchrotron sources, bounces off and is refracted by the sample to determine the positions of individual atoms.

"These structures reveal details of how the peptides bind and guide the development of future inhibitors," said paper co-author Annie Heroux, a biologist and crystallography specialist at Brookhaven Lab.

This structure-assisted design led to the discovery of D-peptides with up to a 40,000-fold improved antiviral potency over previously reported D-peptides. The structures also suggest ways to engineer the peptides to reduce the chance of drug resistance.
